Definitions
- the invention relates to a device for the foaming of milk with external milk suctioning according to the generic term of Claim 1 .
- Such devices are known as an add-on device for connection to the steam supply provided with a steam nozzle of espresso machines or similar household appliances, wherein the device is equipped with a nozzle arrangement provided for the generation of vacuum pressure in a vacuum chamber by means of steam flow and possesses suction tubes separately or jointly conducted and connected to the vacuum chamber for milk and air or milk-air mixture and a discharge opening for the discharge of the generated steam-milk-air mixture and the milk suction tube can be submerged into the milk to be treated, which is located in the container for holding of the steam-milk-air mixture or is located in a separate container.
- the European patent publication EP 1 115 317 A1 describes such a device, in which case via an external milk supply preferably from a separate milk container suctioned untreated milk is mixed with air in a pre-mix chamber and the milk-air mixture flows to the vacuum chamber of a nozzle arrangement and steam flow generated by the vacuum flows via an emulsifying chamber and discharge opening to a receiving container for the generated milk foam.
- the cleaning does not normally take place directly after the use of the device since the user—conditioned also by the presence of additional persons—is more likely to concentrate on the enjoyment of the generated cappuccino or other coffee-milk foam-beverage than on the cleaning task. Moreover, it is often not clear whether an additional use will take place in the immediate time sequence. If the cleaning e.g. does not take place until the next day, the milk residues in between are encrusted and can only be cleaned with difficulty The milk residues that have not been cleaned or only expensively in the interior of the nozzle arrangement and the milk suction tube then become a hygiene problem.
- the object of the invention is to create a device for the foaming of milk with external milk suctioning as an add-on device for connection to the steam supply provided with a steam nozzle of espresso machines or similar household appliances whose operation is possible without expensive cleaning.
- the device is composed of at least one fixed part that can be connected to the steam supply with steam nozzle and one connectable disposable part arranged on the fixed part that can be easily removed from said fixed part, and the disposable part consists at least of a nozzle arrangement arranged in the region of the fixed part with vacuum chamber and suction tubes as well as a milk suction tube and a milk foam discharge tube with mixing chamber.
- the milk suction tube and milk foam discharge tube and in particular embodiments of the invention also the nozzle arrangement are designed essentially as thin-wall plastic tubes that can be cut to size which can be produced by extrusion molding and preferably by thermal deformation.
- the cross-section of the tubes can be circular or designed in another form.
- the nozzle arrangement with vacuum chamber and at least parts of the suction tubes for milk or for milk and air or for the milk-air mixture is formed by at least one nozzle body preferably generated by plastic injection molding, said body being is fastened on its upper end to the fixed part and which possesses outlets for the tubes.
- Nozzle bodies of this type can be produced very cost-effectively by injection molding in multiple forms, also e.g. out of polypropylene. The can also be designed in two parts to avoid expensive molding technology due to necessary gate valves.
- the nozzle arrangement with vacuum chamber and at least parts of the suction tubes are formed in a further special embodiment of the invention essentially by a thin-wall multiple tube section which can be produced by extrusion molding consisting of at least two plastic tubes arranged axis parallel to each other and joined to each other with at least one joint wall element, wherein at least the milk suction tube can be connected to one of the tubes and another of the tubes serves at least the purpose of supplying the steam flow and discharging the milk foam flow.
- the nozzle arrangement with vacuum chamber and at least parts of the suction tubes can in a preferred embodiment of the invention be formed by indentations and bulges on the multiple tube section which can be generated by thermal deformation. With this the manufacturing expenses for the nozzle body are omitted and an overall very cost-effective solution results.
- thermoplastic tube section made of a thin-wall tube similar to the milk suction tube and milk foam discharge tube and fastened in the milk foam discharge tube lies within the scope of the invention. This forms on its exterior to the wall of the milk foam discharge tube a torus into which the milk and air streams flow, mix with each other and after that enter the vacuum chamber.
- the tube section is preferably arranged in one of the tubes of the multiple tube section.
- the disposable part is formed in specified embodiments of a plurality of component parts, wherein the component parts can be joined together expediently by means of an assembly machine quite cost-effectively and can be connected to each other by clamping, bonding, selective hot forming or welding e.g. by ultrasound or laser.
- the nozzle arrangement for generation of the vacuum pressure necessary for the suctioning of milk and air can consist of a venturi tube with vacuum chamber in the bottleneck or of an open jet nozzle, such as e.g. used in spray cans, wherein the open jet in the case of an erratic cross-section expansion of the nozzle to the vacuum chamber brings about a suctioning in its exterior region.
- suction tubes for milk and air can be conducted in completely variable manner within the scope of the invention. It is advantageous in this connection if the air is first mixed with the milk before the milk is suctioned from the steam jet.
- the steam nozzle forms the termination of the steam supply.
- the fixed part can in another embodiment of the invention also be clamped with a clamping device, wherein in another embodiment of the invention the disposable part can be slid over a tubular formation of the fixed part and clamped.
- the air flow into the supply tube can be blocked in the region of the fixed part or of the milk suction tube. With this the user can choose whether he wants to heat and foam the milk or only heat it.
- the milk flow or the milk-air flow can be adjusted quantitatively.
- the air flow can be supplied via an air-core choke arranged in the region of the outlet of the milk suction tube on the nozzle body in the wall of the milk suction tube.
- the air-core choke consists of a preferably circular constructed opening or recess in the wall whose cross-section of flow corresponds to a diameter of 0.2 mm to 0.8 mm of a circular opening, preferably 0.3 mm to 0.6 mm recesses or openings with non-circular form (e.g. elliptical or quadratic form) thus requiring a correspondingly dimensioned cross-section.
- the opening can be produced by means of thermal deformation of the thin-wall milk suction tube (thus e.g. by injection of a mandrel heated with corresponding diameter).
- a flavor dispenser is integrated into the disposable part, which flavors are dissolved by the steam flow and/or the milk flow and are carried in the milk foam.
- flavors are dissolved by the steam flow and/or the milk flow and are carried in the milk foam.
- it can for example be a matter of a taste change of the milk or the milk foam into a “Viennese blend” coffee.
- the object of the fixed part according to the invention in the case of an intended use not moistened with milk is to be able to design the disposable part as simple, small and cost effective as possible and to make its combinability with the steam supply as convenient possible.
- the fixed part can on the other hand be designed more expensively, since it is not designed by milk for permanent usage.
- An additional advantage of the fixed part is the fact that the disposable parts can be identically designed for use at different espresso machines, since the differences between the espresso machines are then covered by the in that case variable fixed parts. This simplifies the marketing of the disposable parts.
- espresso machines are available in great number with identical outlet measurements at the steam supply equipped with steam nozzle for equipping with single use foam nozzles, the use of fixed parts is expensive, since these are all identically designed.
- the fixed part into the steam supply or into the steam nozzle forming the termination of the steam supply and therefore suitable design the steam supply (e.g. designed as a tube) or the steam nozzle as termination of the steam supply for the coupling of the disposable part.
- the steam supply e.g. designed as a tube
- the steam nozzle as termination of the steam supply for the coupling of the disposable part.
- the plastic tube (preferably steam tube or multiple tube section) supplying the steam flow of the nozzle arrangement possesses for this purpose a shape on its upper end with steam inlet which permits a connection to the steam supply or the steam nozzle that can quickly be established and detached again.
- the steam tube is expanded as termination of the steam supply in the region of the outlet. This expansion can be omitted if the steam supply itself is designed as a fixed part.
- the inner diameter of the steam tube in the region of the outlet in preferred embodiment corresponds approximately to the outer diameter of the steam supply or the steam nozzle and is preferably fixed on the fixed part by means of locking ring/locking groove using the elastic expandability of the steam tube.
